As the cable news channels count down the hours before the first polls close on Tuesday, an entire election cycle will have passed since President Obama last sat down with Fox News. The organization’s standing request to interview the president is now almost two years old.

At NBC News, the journalists reporting on the Romney campaign will continue to absorb taunts from their sources about their sister cable channel, MSNBC. “You mean, Al Sharpton’s network,” as Stuart Stevens, a senior Romney adviser, is especially fond of reminding them.

Spend just a little time watching either Fox News or MSNBC, and it is easy to see why such tensions run high. In fact, by some measures, the partisan bitterness on cable news has never been as stark — and in some ways, as silly or small.

NBC News edited a 911 tape of George Zimmerman in a way that implied race as a factor in the Trayvon Martin shooting. CNN and Fox News falsely reported that the Supreme Court had struck down the individual mandate at the heart of the Obama administration’s health care law. ABC News wrongly suggested a link between a mass shooting in Colorado and the Tea Party. Just last week during the storm, CNN repeated a false rumor about flooding at the New York Stock Exchange.

Now the media are gearing up for election night, the finale of the year’s biggest story. It’s a chance to regain some credibility — presuming, of course, that television networks and other news organizations get their state-by-state projections right. They all say they will, still mindful of the mistakes made in 2000, when the networks prematurely called Florida for Al Gore and then George W. Bush.
